" Application filed July 15, 1914. Serial No. 851,088.

To all whom it may concern Be it known that we, ALONZO and CHARLES HERBERT BLAoK, citizens of the United States, and residents of Des Moines, county of Polk, and State of Iowa, have invented certain new and useful Improvements in Stovepipe-Sections, of which the following is a specification.

This invention relates to an improved reducing stove pipe section which will serve to connect a stove pipe witha stove open-- ing which is of a different size than the opening in the pipe, and one of the objects of the invention is to provide an improved section of this character, provided with an oval opening at one end to fit the stove collar and a circular or round opening at the other end, and to which latter end the stove pipe is connected.

A further object is to provide an improved, simple, durable and compact device of this character which will be eiiective and eflicient in operation and which is of sectional construction, whereby the device may be knocked down or collapsed and the parts nested for shipment purposes.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and ar rangement of the several parts, hereinafter more fully described and claimed, and shown in the accompanying drawing illustrating the invention, and in which Figure 1 is a front elevation of a portion of a stove and stove pipe, having a pipe reducing section, constructed in accordance with the principles of this invention, connected thereto. Fig. 2 is an end elevation of the joint. Fig. 3 is a sectional view on line 3-3, Fig. 1. Fig. i is a perspective view of the sections of the stove pipe section slightly separated and with a portion broken away.

Referring more particularly to the drawing and in the present form of the invention, the section comprises two sections 10 and 11, each of which sections is provided with tongues or ears 12 extending therefrom, preferably from one of the longitudinal edges thereof, and each section is also provided with slots 18 adjacent another longitudinal edge and the ears 12 of one C. BLACK the section is connected.

section are disposed opposite the slots of the other section, so that when the sections are placed together, the ears of one section will enter the slots of the other section and the fastening means for the sections being spaced a considerable distance from the ends of the pipe section, permits the extremities of the respective sections to have a lateral movement with respect to each other to insure a tight fit with the pipe to which When the parts are thus assembled, the ears 12 may be defiected or bent as shown in Fig. 3 so as to securely hold the sections together.-

One extremity of the section thus formed is round or circular in configuration as at 14, while the other end 15 of the section is shaped so that when the section is assembled, the end will be oval as shown in Fig. 3, and this other extremity is adapted to be placed over the flange 16 which surrounds the opening in the stove 17. The circular extremity of the section is preferably corrugated as at 18 and this corrugated extremity is adapted to be inserted into the end of the stove pipe 19. If desired the section may be provided with a corrugation or grooved rib 20 to form a stop against which the end of the stove pipe 19 rests when the parts are assembled and when the sections are assembled, the rib of one section will enter the groove in the rib of the other section.

The body portion 21 of the section tapers from one of the openings toward the other so that it will be reduced in size and so that it will fit snugly within the pipe 19.

With this improved construction, it will be manifest that the necessity of cutting off the ordinary tapering section is dispensed with and insures that the section will always be of the proper size to fit the stove pipe and opening of the stove, and the section being sectional in construction, the sections may be separated to divide the section longitudinally and these sections then nested for shipment purposes.

Both of the parts of the section being of a similar construction, obviates the necessity of constructing the parts in rights and leftsl While the preferred construction and manner of assembling and securing the parts together is herein shown and described it is obvious that many changes may be madein the details of construction Without departing from the spirit of this invention.

What is claimed as new is A stove pipe section, one end of Which is.

5 round and the other end oval in shape, the

' adjacent one of its longitudinal edges, there being slots adjacent the other longitudinal edge,.the slots of one section receiving the ears of the other section, for detachably securing the sections together, said ears and slots being disposed intermediate the said straight portions and spaced a considerable distance from the ends of the section so that the ends of'the sections will have a lateral movement with respect to each other, and the said straight portions being of uniform diameter throughout their length, and a grooved ribformed in each endof the section at the base of said straight portions, portions of the rib of one section entering the groove in the rib of the other section when the parts are assembled to form a continuousstop for apipe section.

In Witness whereof, We hereunto subscribe f our names to this spec fication 1n the presenceof two witnesses.
